Jay: If your question is about supernumerary breasts, it is not uncommon for people (both men and women) to have extra nipples (in the case of women, occasionally extra breast tissue as well), along what is known as the "milk line", which runs from the armpit down to the groin. That is what supernumerary means, just a fancy term for "extra". In some women with this condition, they may not realize they have this extra tissue in their armpit until they get pregnant and have the baby, when this tissue swells at the same time as the breasts, and they think they've developed a tumor or something.
